Domain Name Server (DNS) Configuration
Use domain name servers when the switch needs to resolve a domain
name (such as nortel.com) to an IP address. Use the following commands
to configure the switch domain name servers:
•
"show ip dns command" (page 192)
• "ip domain-name command" (page 192)
•
"no ip domain-name command" (page 192)
• "default ip domain-name command" (page 193)
• "ip name-server command" (page 193)
• "no ip name-server command" (page 193)
show ip dns command

show ip dns
command to display DNS-related information. This
information includes the default switch domain name and any configured
DNS servers.
The syntax for this command is
show ip dns
Run this command in User EXEC command mode.
ip domain-name command
Use the
ip domain-name
command to set the default DNS domain name
for the switch. This default domain name is appended to all DNS queries or
commands that do not already contain a DNS domain name.

ip domain-name <domain_name>
Substitute
<domain_name>
with the default domain name. A domain
name is deemed valid if it contains alphanumeric characters and at least
one period (.).

no ip domain-name
command to clear a previously configured
default DNS domain name for the switch.
